To allwhomitmaycomem: a

Be it known that I, WILLIAM A. GEIGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Impr vement in Roller Side Bearings" for Railway-Cars, of Whichthe' following is a full, clear, concise, and exact description, reference being had to' the accompanying drawings, forming a part of this specification.

This invention relates to improvements in roller side bearing for railway cars.

The object of the invention is to provide a side bearing for railway cars which consists of few parts that may be cheaply and easily manufactured and assembled and which will provide a bearing efficient in operation.

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices as herein shown, described or claimed. And although I herein show and describe in detail one form of my improvements, yet I do not wish to be confined to the details shown and described, inasmuch as I am aware that various changes and modifications may be made in the arrangement and details of the parts without departing from the spirit of the invention,

and I contemplate all such changes and modifications as fall within the scope of the claims forming a part hereof.

In the drawing, Figure 1 is an elevational view of a body and truck bolster of a railway. car, showin my improvements in con:

nection therewit Fig. 2 is an enlarged vertical sectional view taken substantially on the line 2-2 of Fig. 1, and showing more articularly the improved side bearing, and Fig. 3 is a similar sectional view taken substantially on the line 3-'3 of Fig. 2. a In said drawing 10 denotes the truck bolster which is swiveled in the usual manner to the body bolster 11 and, as shown, the

body bolster is provided with an integral bearin plate 12 on each side of the king pin. oiiperable with each bearing plate 12, is one of my improved roller bearings, designated generally by the reference A. As shown, the roller bearing A comprises a base plate or bracket B and an anti-friction roller C. The bracket B has a horizontal base 14 riveted or otherwise suitably secured to the truck bolster 10. Extending up-' nal is held in position and prevented from accidental displacement by means of strips 18 inserted through suitable slots formed in the extensions 19-19, the strip having its ends bent down as indicated at 20. The journal 17, as shown, is provided at the center thereof with an enlargement 21, which is of substantially spherical Jformation.

.The roller C comprises two like members 2222, each of which is in the form of an annular disk with an opening through the center thereof, which opening consists of a flared portion 23 and a concave bearing surface 24 corresponding to the 1 spherical surface of the enlargement 21. On the inner face of each member 2222, is provided a pair of sockets 25 and a pair of outstanding dowels or pro ections 26, it being] obvious that the pair of dowels on one member 22 fit in theborresponding sockets of the opposite member 22 and in this way prevent relative rotation of the members Said sleeve 27 is provided at each edge with an inturned flange 28 which fits in corresponding grooves or recesses 29 on the outer sides of the members 22.

From the precedin description it will be seen that the roller is permitted not only to rotate about the journal 17 but also to oscillate thereon to thus accommodate itself to the varying angular positions of the body and truck bolsters and the sleeve 27 provides a hardened wearing-surface without the necessity of making the entire roller of the same hard material, thus minimizing the cost of manufacture.

I claim 1. Alroller side bearing of the character described comprising, a bracket having a journal mounted thereon, and a roller rota- .tably mounted on said journal, the roller consisting of two circular members and a circumferentially extending shell inclosing and overlapping the side of said members to thereby unite the same.

2. A roller side bearing of the character described comprising, a bracket having a journal mounted thereon, a roller rotatably mounted on said journal, the roller consisting oftwo circular members and a circumferentially extending shell inclosing and overlapping the sides of said members to thereby unite the same, and cooperating means on the interior of the roller and on the journal permitting the roller to oscillate in addition to its rotative movement.

3. in a roller side bearing for railway cars, the combination with a supporting bracket having a journal mounted thereon, of a roller mounted on said journal, said roller comprising two circular members having interfitting dowels and sockets on their meeting faces and a sleeve for hoiding said members in assembled position.

4. In a side bearing for railway cars, the combination with a base bracket, of a journal mounted in said bracket, said journal having a spherical enlargement .near the center thereof, and a roller having a trans- 5. In a side bearing of the character described, the combinatlon with a supporting bracket having upstanding, spaced arms, each of which is provided with a journal bearing near the top thereof and open at its upper end, of a journal mounted in said bearings, said journal having a spherical enlargement near the center thereof, and a roller rotatably and rockably mounted on said journal, said roller comprising two circular members having interfitting projections and sockets on their meeting faces and a sleeve encircling said members and flanged at its edges to bind said members together.
